Why do particle trails randomly change color during their lifetime ? It looks like flickering in render. I have simple material assigned to emitter with octane tag. Gradient → Colorizer plugged into diffuse channel.
How can I get rid of this ?

I am using parallel projection on octane camera but live viewer shows cropped view compared to viewport. Zoom factor is set up to 1 so I have no idea where this difference is coming from.
